I have found that incandescent lights give off heat as well as light energy. The higher the wattage of the light bulb the higher the temperature. A compact fluorescent bulb gives off very little heat energy because they do not use resistance and cause a light to glow hot. In a home or office, lots of incandescent lights means that the air conditioner would have to use more energy during the summer to remove the extra heat given off by lights. Also, some lights such as torchieres, can be very dangerous as the bulbs are rated at 300 watts or more and get VERY hot. They can catch drapes or other materials on fire if you're not careful.
